How to Test a Small Engine for Spark
If your small engine isn't starting, you'll need to diagnose many issues including the spark plug. This video walks you through the steps of how to test for a spark using a spark tester.

I have a Karcher G2600VH pressure washer that is about 2 years old. The engine starts and idles fine, but as soon as the trigger is pulled acts like it has no power. I've had the engine looked at by a small engine shop and they cleaned the carb but could not find anything else wrong with the engine. Could I possibly be looking in the wrong place? I'm starting to wonder if I may actually have a problem with the pump instead. Any help would be greatly appreciated.

Hello 1204008,

I have a Kratcher G2600 which lost pressure.
I pulled the spill valve an it was broken. Ordered a new one and replaced it. Now I have rapid pulsating. I checked the nozzle and water flow, all OK. What should I check next.

My Karcher G2600 VH started the rapid Pulsating Pressure problem. Can you point me in the correct direction to find the most common failure that will cause this problem.

I have watched the repair videos but will wait to disassemble the pump when i have an idea of what to look for...

Thanks

Hello bobwojo48,

One of the most common repairs on pressure washers is the 4.591-040.0 Spill(Unloader) Valve failing. One other thought, is to make sure that you have enough water entering the pump. The pump needs to have an adequate supply of water, or it will run sporadically.

I have a 2 year old Karcher G2600 VH. Intermittent use, mainly cleaning siding and gutters.

While washing gutters yesterday it surged under use, but not all the time. It acted like it had air in the line, but water supply was good, and the problem came and went. I was able to finish my project, but at the very end, the pump started pulsing, for want of a better word, very rapidly, and water started leaking from the general area where the three main components of the pump join together.

I did pull the spill valve, after watching the Youtube video. It appeared clean, with no visible deposits or other problems. I reassembled it, hooked up the water supply, and the pump again leaked, with the engine not running.

What should my next step be? I'd like to repair this myself if possible.

I have a Karcher g 2600 VH. The pump shaft and swash plate seem to be one piece. The parts breakdown show the swash housing and shaft as two parts attached by a bolt. Can anyone shed some light on this?

The pump shaft has a domed insert inside the shaft instead of a bolt as shown in the diagram. The shaft is pressed inside the inner bearing race but it's not a tight fit. It can be tapped out be using a socket that just fits inside the shaft. The seal at top of the casting can be removed in a similar manner.
